Purity ~90% (SDS-PAGE). Binds specifically to cytosolic chaperonin (c-CPN) and transfers target proteins to it. Binds to nascent polypeptide chain and promotes folding in an environment in which there are many competing pathways for nonnative proteins. Represses the transcriptional activity of MYC. Source: Recombinant protein corresponding to aa2-154 from human PFDN5, fused to GST-Tag at N-terminal expressed in E. coli. Molecular Weight: ~44.2kD AA
